Application
The MS3 micro switch is a control switch commonly used in drain pumps and other equipment with self-locking and protective features. The microswitch is connected to the water circuit and the pressure generated when the pump is working is transmitted to this part, which is connected in series with the heater circuit and is turned on only when there is pressure, preventing dry burning situations from occurring. The switch is manufactured with high quality materials for durability and stability, ensuring stable operation of the unit for long periods.
the MS3 micro switch adopts advanced technology and design, which is able to work normally in harsh environments, with waterproof and dustproof features, and can adapt to a variety of working environments.
